| 摘要: 在室温下，AgNO3、1，3-二(4-吡啶基)丙烷和2,5-噻吩二甲酸在丙酮水溶液中反应,经数周后得到完整无色晶体[Ag(bpp)]2(tdc)·8H2O。该晶体由荷正电的类似正弦曲线形状的配位聚合物链，[Ag(bpp)]∞，和有机负离子tdc2-构成,其间分布着起重要作用的结晶水分子。相邻的阳离子链通过静电作用与tdc2-阴离子堆积构成晶体的三维骨架, 结晶水分子分布其间并形成氢键，对晶体堆积起定位作用。[Ag(bpp)]2(tdc)·8H2O的晶体学数据:单斜晶系,空间群C2/c，a=3.544 7 nm，b=0.920 03 nm，c=2.411 9 nm，β=106.56°，V=7.546 nm3和Z=8；残差因子R1=0.046 3，wR2=0.114 2。UV/Vis/NIR漫反射光谱法测定表明其具有很强的选择性光吸收特性。 |

| Abstract: The reaction of AgNO3, 1,3-bis(4-pyridyl)propane, thiophene-2,5-dicarboxylate in acetone aqueous solution produces block colourless crystals [Ag(bpp)]2(tdc)·8H2O at room temperature. [Ag(bpp)]2(tdc)·8H2O consists of parallel sinusoid-like cationic chains, [Ag(bpp)]∞, interspersed with organic tdc2- anions which play the role of charge compensation in the crystal structure. The lattice water molecules are situated among these chains and stabilized by rich hydrogen-bonding interactions and lattice water molecules may play a role in the orientation of the tdc2- in the crystal packing. The crystal data: monoclinic C2/c, a=3.544 7 nm, b=0.920 03 nm, c=2.411 9 nm, β=106.56°, V=7.546 nm3, Z=8. The residual factors based on 6 563 reflections (Rint=0.056 7) are R1=0.046 3, wR2=0.114 2. Optical absorption properties and band gaps of title compound were determined with UV/Vis/NIR diffuse reflectance spectra. CCDC: 286751. |
